IMPROVEMENT IN RAILWAY-RAIL JOINTS.

Specification forming part of Letters Patent No. 147,270, dated February10, 1874; application filed November 22, 1873.

To all whom it may concern:

Be it known that I, ADOLPHUS J OIINSON, of Uhricksville, county ofTuscarawas and State of Ohio, have invented certain Improvements inRail-Joints for Railways.

The following description, taken in connection with the accompanyingplate of drawings hereinafter referred to, forms a full and exactspecification, wherein are set forth the nature and principles of theinvention, by which the same may be distinguished from others of asimilar class, together with such parts thereof as are claimed as newand are desired to be secured by Letters Patent of the United States.

My invention relates to that class of fastenings or couplings which aremade use of for connecting the joints of rails; and the nature thereofconsists in certain improvements in the same, hereinafter shown.

In the accompanying drawing, which i1lintrates my invention and forms apart of the specification thereof, Figure l is a side elevation of therails with my invention applied thereto. Fig. 2 is a longitudinalhorizontal section taken in the line a a, Fig. 1.

In the said drawing, A A designate two rails to be secured together, ineach of which are cut oblong apertures, through which pass the wedges Band the key-pieces O. D indicates fish-bars, secured to each side of therails, and provided with apertures for the reception of the said wedgesand key-pieces, which are secured together by the pins (7, which fit inreceptacles formed by cutting semieylindrical slots in the same, asshown in Fig. 2. In the key-pieces are cut the slots h, the sides ofwhich are beveled, so that when the wedges. c are driven in thekey-pieces are caused to tighten against the fish-bars. The apertures inthe rails are larger than the apertures in the fish-bars, in order togive the rails an opportunity to expand.

Having described my invention, I claim- The combination of the rails,fish-bars, keypieces, wedge-pieces, and pins, all operating together asdescribed.

In testimony that I claim the foregoing I have hereunto set my hand this27th day of October, 1873.
